On the street i ususally drop it around 3000. Also im upgrading to 4.10s so once i put them in how much lower should i drop my rpms to launch. Not running heads or cam if you were wondering.

drop it until it rotates the tire about 1/4-1/2 a spin and then hooks

Every car is different - test yours and find the sweet spot.

If you're still on the stock 10 bolt, I'd highly suggest not dumping the clutch at all.

If you put 4.10s in the stock 10 bolt you should launch off idle.

Basically...you need to upgrade to a 12-bolt then just practice

I have full bolt ons and 4.10s, I usually launch at about 2500 and still have a 10bolt in there, I cut mid 1.8 60fts on nittos, so thats pretty good till I can afford a 12bolt.

well the $2000 dollar 12bolt or 9inch you guys think i should just magically throw in would be nice but since im 20 and going to school thast kind of out of the question. I would love to do it though. I guess ill stick to what ive been tryin and hope for teh best.

Ok, break your rear end. You'll be a 20 year old, going to school w/ a busted TA. :jest:

keep the 3.42's and you'll be fine for a while. I was cutting mid 1.80's on my 315/35/17 drag radials for about a year and my 10bolt didnt even whine. If you got $150 layin around, invest in a girdle kit.
